Specification of Letters Patent.

Patented June 28, 1921.

Application filed December 3, 1920. Serial No. 428,078.

To all whom it may concem:

shells of this kind in such wise that the hood does not injure the effect of said cap.

On the drawing a construction ofthe subject matter of the invention is shown by way of example.

Figure 1 shows thepoint ofthe shell in elevation with the cap and the hood in section, a I

Fig. 2 shows the corresponding top view, partly in section on line 22 of Fig. 1.

The point ofthe shell A carries an obtuse cap B. On the cap B there is fixed by screw threads a thin-walled hood 0, which has a form favorable to overcome the resistance of the air. Further, the hood 0 is provided with a number of perforations 0 which are arranged at equal distances around the entire periphery of the hood.

Experiments have demonstrated that under otherwise equal conditions (equal striking energy and equal angle of incidence for instance) capped projectiles the hood of which has the described perforations have a hitting the target at acute striking angles,

considerably increased effect especially when with respect to capped shells the hood of which has no perforations.

Claims: v V 1. Armor-piercing shell having a cap and a hollow hood projecting beyond the said perforations. I

2. Armor-piercingshell having a cap' and cap, said hollow hood being provided with a hollow hood pro ecting beyond said cap,

said hollow'hood being provided with perforations, arranged at equal distances around the entire periphery'of the hood.
